All strengths are calculated theoretical yield points and are accurate within 20%. All strengths assume straight, steady pull and full grapple engagement of a round fish. 

Anything less than full engagement or straight pulling, will reduce the listed strength. 

Tong marks or other damage to the bowl surface will also reduce the listed strength. 

All torque calculations are theoretical maximum tightening torques for the threaded connection and do not include clamping force. Clamping force is not considered 

due to the variety of devices used to tighten these connections. 

CAUTION: Due to the amount of torque applied to a connection and the type of device used to apply the torque, damage to the bowl, top sub, or guide may occur.

1) All strengths are calculated theoretical yield points and are accurate within 20%. All strengths assume a straight, steady pull and 

full grapple engagement of a round fish. Anything less than straight pulling or full engagement will substantially reduce the strength. 

2) No tong marks should be applied to the bowl. Tong marks and other surface damage to the bowl will also reduce the strength. 

3) Maximum recommended makeup torque is 50% of yield. Less torque may be used depending upon the situation. 

4) Jarring may amplify the pull load by a factor of 3 to 10.

* The drill collar number (first column) consists of two parts separated by a hyphen. The first part is 

the connectlon number in the NC style. The second part, consisting of 2 (or 3) digits, indicates the 

drill collar outside diameter in units and tenths of inches. The connections shown in parentheses in 

the first column a not a part of the drill collar number; they indicate interchangeability of drill collars 

made with the standard (NC) connections as shown. If the connections shown in parentheses in 

the first column are made with the V-0.038 R thread form (as provided in Par. 9.4) the connections, 

and drill collars, are identical with those in the NC style. Drill collars with 8-1/4 and 9-1/2 inches 

outside diameters are shown with 6-5/8 and 7-5/8 Regular connections, since there are no NC con- 

nections in the recommended bending strength ratio range.

Connector Sub or Drill Collar 

Suggested Marking 

1. Thoroughly clean with distillate, pin and box threads and shoulder. After cleaning, the joint must 

be dried before lubricant is applied. 

2. Coat all areas of the pin and box threads and shoulders with a thin even coat of a good grade 

lubricant from a covered or newly opened can. A molydisulfide lubricant is recommended. 

3. Extreme care should be used when stabbing the joints to avoid stabbing wounds. If drill collar 

connecting subs are used, it is preferred that the subs be applied by hand rather than with lifting 

equipment. 

4. Make up joints manually with chain tongs as far as possible and then use cathead to the full 

recommended torque as shown on attached chart. 

5. Scribe vertical chalk line across joint make-up line of box and pin faces. 

6. Break joint, clean and dry threads. Inspect the threads and joint faces carefully for evidence 

of galling or “hair like” slivers of steel. Stone or file all rough spots and remove slivers. Be careful 

not to remove chalk line across joint face. 

7. Again make up joints manually with chain tongs as far as possible and then with cathead using 

full recommended torque. The joint must make up to the chalk mark or father. If the joint does not 

make up to this line, again break the joint, dry and clean. Inspect the threads and joint faces care- 

fully and in general proceed as under 6 above. 

8. If the joints make up to the chalk line or farther, a center punch mark shall be made on both the 

box and pin halves, adjacent to the shoulder, as permanent inspection mark. After each run, these 

match making spots should be inspected and as long as there is no creep between the two marks, 

the joints should be left unbroken if possible (nonworking joints). As the drill collars wear, it is 

recommended that the center punch marks be deepened so that they will always be in evidence. 

When it is noted that creep has occurred on the nonworking joints, they should be broken apart, 

inspected and if necessary recut.

The use of outside diameters (O.D.) smaller than those listed in the table may be acceptable on Slim Hole (SH) tool joints due to special service requirements. 

Tool joint with dimensions shown has a lower torsional yield ratio than the 0.80 which is generally used. 

Recommended make-up torque for used tool joints is based on 72,000 psi stress. Recommended make-up torque for used tool joints that have not worn to the 

minimum O.D. can be obtained as described in Par. 2.12. 

In calculation of torsional strengths of tool joints, both new and worn, the bevels of the tool joint shoulders are disregarded. This thickness measurement should be 

made in the plane of the face from the I.D. of the counterbore to the outside diameter of the box, disregarding the bevels. 

Any tool joint with an outside diameter less than the API bevel diameter should be provided with a minimum 1/32" depth x 45° bevel on the outside and inside 

diameter of the box shoulder and outside diameter of the pin shoulder. 

p = pin limited yield. b = box limited yield. P or B indicates that tool joint could not meet 80% of tube torsion yield. 

* Tool joint diameters specified are required to retain torsional strength in the tool joint comparable to the torsional strength of the attached drill pipe. These should be 

adequate for all service. Tool joints with torsional strengths considerably below that of the drill pipe may be adequate for much drilling service.

API has taken all flanges that used an R or RX ring gasket and typed them as 6B. They have taken 

all connections that use BX ring gaskets and typed them 6BS. Exceptions to this are as follows: 

The old S/2900 is considered obsolete by API and is not included in their designations. This series, 

because it is 10,000 psi working pressure and uses either an R or RX ring gasket, does not conform 

to the system that API has used to rename flanges. Therefore, for simplicity, and since the R and RX 

ring gaskets are used in the S/2900, the S/2900 is designated as a type 6B. The other exception is 

the new 13-5/8" 5,000 psi flange. API has arbitrarily designated these as a 6BX flange, although the 

working pressure is 5,000 psi and BX ring gaskets are used.

Multiple line hookups can provide many times 

the normal make-up line-pull. Great care should 

be taken to see that the lines do not become 

crossed, twisted, or fouled. When it comes time 

for the “big pull,” be sure everyone is in the clear. 

Caution: Know the tong’s rating before the 

pull is attempted. 

The slack in the tong snub line should be sufficient 

for the tongs to obtain full benefit of the pull 

from the cathead, but short enough to pre-vent 

complete rotation of the tongs.

how to Measure Wear on Elevators and tool Joints 

It is obvious that visual inspection cannot suffice for most 

elevator checks. To measure link arms it is necessary to 

use calipers and to read the result on a rule. Since significant 

wear is restricted to the top link arm, it is here that 

the measurement is taken. 

Hinge pins, latch pins, and socket holes are not normally 

measured for wear in the field. When it becomes apparent 

that the hinge or latch pins are loosening, the elevator 

should be sent to the factory for a general engineering 

check-up. 

For square-shoulder elevators, a rule marked in sixteenths 

of an inch is adequate. The straight edge of the rule is 

used to check the squareness of the top bore, and the 

end is inserted into the worn pockets and ridges. Wear 

of 1/16 in. or more should require re-facing of collar surface. 

The squareness of tool joints (where collar meets 

the pipe) may be checked using the right angle formed 

by the rule end. Joints out of square by 1/16 in. or more 

should be reconditioned or replaced according to recommendations 

of manufacturer. 

Determining wear of the 18° taper elevator and tool joint 

is more difficult. As shown in Figure 1, an arm containing 

a true 18° surface is extended into and matched against 

the elevator bore. At the top of the bore, the actual angle 

is read off a protractor attached to a straight edge. The 

same principle is used for tool joints. In Figure 2, the 

straight-edge is placed on top of the tool joint and the true 

18° surface is placed along the tool joint taper. 

Figure 

Figure 

Figure . To measure elevator taper, a true 18° surface 

is inserted on an arm into the elevator bore and matched 

against the taper. Result is read on a protractor attached 

to a straight-edge. 

Figure . To measure tool-joint taper, a true 18° surface 

is matched against the taper and the result read on a protractor 

mounted on a straight-edge at the top of the tool 

joint. Hardbanding should also be checked for violation 

of this taper. 

Since these tapers do not wear evenly, it is necessary to 

use the smallest angle of contact found. 

Inspection gauge for Elevators and tool Joints 

Recognizing the importance of an accurate measurement 

and appreciating the difficulty in constructing an instrument 

as described, Cooper Industries, Inc. has engineered and 

manufactured a permanent aluminum gauge. 

This instrument permits many measurements and calculations 

without reference to supplementary data. 

Evaluation of Wear 

Once the degree of wear has been ascertained, the evaluation 

is conducted as follows: 

The effect of wear on 18° taper elevators and tool joints 

may be determined by using Figure 3. Entering chart at 

actual angle of taper, read across to diagonal reference 

line and down to base of chart. The result is the percentage 

to which an elevator capacity is reduced by such worn 

tapers. Example: Inspected tool joint was found to have 

a taper of 13°. As it was to be used with a perfectly sound 

250-ton elevator, the elevator capacity was reduced to 

78%, or 195 tons.

periodic Inspection (See ApI Rp8B) 

This examination, as outlined below, whether conducted 

in the field or shop, should be made using calibrated 

instruments to determine any deviations from the manufacturer’s 

technical data for original parts. 

Square Shoulder Collar-type Drill pipe, Casing, 

and Standard tubing Elevators: Inspect the collars for 

squareness, and uniformity and depth of wear. Uneven 

wear, or worn recesses of 1/16 in. or more, requires refacing 

of collar surface. Hinge pins and springs should be 

carefully inspected visually for excess wear and obvious 

weakness. 

8° taper-type Elevators: Inspection is the same as for 

square shoulder, except that the conical bore should be 

observed and measured (in many instances this check 

should be more frequent.) All tool joints used with these 

elevators should be measured. Amount of wear should be 

checked with chart, Figure 3. In addition to the angle of 

taper, hardbanding should be checked to see if it extends 

beyond the taper. Any straight-edge may be used for 

this purpose.

Determining if an elevator is safe or unsafe, satisfactory for use or ready for repair, should not be entrusted to the eye! 

Such determinations require accurate measurements of the critical elevator parts. 

Link Arm

to MEASuRE AngLE oF 8° tApER ELEVAtoRS: Place body of gauge 

on top of elevator bore, and drop sliding arm into the bore. Bring tapered 

edge of slide (marked “Elevator Taper”) against tapered surface of the bore. 

Read true taper angle of elevator bore at “H.” Percentage of remaining rated 

capacity is given opposite the reading. Tapers of 13° and less require factory 

reconditioning, or retirement from service. NOTE: Bores do not wear evenly. 

Use the smallest angle found. 

to MEASuRE AngLE oF 8° tApER tooL JoIntS: Place body of gauge 

on top shoulder of tool joint “box.” Sliding arm is adjusted so that the tapered 

edge (marked “Tool Joint Taper”) is in contact with the tapered surface of the 

tool joint. The true angle is read at “H.” Percentage of remaining rated capacity 

of the elevator is given opposite the reading. Again, use the smallest angle 

found. Tool joints of less than 13° should be repaired or replaced. 

WARNING: Even though the elevator may be in perfect condition, 

a worn tool joint taper reduces its rated capacity! 

While inspecting the tool joint, lay any straight edge of the gauge along the 18° 

taper to check that the angle of taper has not been violated by hardbanding. 

Should hardbanding extend onto the taper, such banding should be removed; 

and the elevator that was used with such a tool joint should be inspected for 

damaging wear.

ELEVAtoRS: Place body of gauge on top surface of elevator. Using nontapered 

end of sliding arm, drop arm end into the worn area. Depth of wear is 

read on the “1/4-inch” scale where body and sliding arm cross. Shoulders worn 

more than 1/16 inch should be re-faced by machining. Any rolling of the edge 

into the bore should be removed so that it will not interfere with the closing of 

the elevator.

To determine the strength of worn links, measure the amount of eye wear with calipers as shown, 

and compare the figure with the table for the new capacity. Capacity of set is that of weakest eye. 

Measure the depth of the link ear at the 

point of the greatest wear (Dim. A). The new 

capacity of the hook and/or link ears is 

shown in corresponding chart of hook size. 

WEAR LIMItS: It is recommended that 

any hook showing wear of 1/2" be promptly 

repaired. Wear should never exceed 3/4". 

When properly built up to recommended 

dimensions, the wear pad will prevent further 

loss in capacity until original wear point is
